Scientists reveal Tintina Fault may rupture, posing quake risk in Canada’s Yukon territory

A groundbreaking study by the University of Victoria sheds light on the underestimated seismic threat of the Tintina Fault in northwestern Canada's Yukon Territory. Once deemed dormant for over 40 million years, this fault could provoke massive earthquakes, posing significant risks to nearby communities such as Dawson City, according to a report in SciTechDaily.

Stretching approximately 1,000 kilometers, the Tintina Fault has captivated scientists with its newfound potential for seismic activity. Using cutting-edge topographic imaging from satellites, aircraft, and drones, researchers detected large earthquakes along a 130-kilometer segment of the fault during the Quaternary Period, indicating an ongoing threat, as reported by Juneau Empire.

Historically, few small earthquakes hinted at the fault's latent power. Nevertheless, the advanced data motivated closer examination, revealing surface ruptures capable of significant geological upheaval.

The Tintina Fault's proximity to vital infrastructure raises concern for local communities. Dawson City, located less than 20 kilometers from the fault, risks being battered by powerful tremors that may jeopardize key roads and mining operations. Landslides could further threaten the Klondike region, warns study lead Theron Finley, as cited in Daily Galaxy.

The research highlights the critical need for comprehensive fault monitoring. Existing seismic models fail to include the Tintina Fault, leaving infrastructure such as highways and the Trans-Alaska Pipeline vulnerable.

Future plans could involve trenching to explore seismic histories further, though specifics remain unplanned. Jan Dettmer, Geoscience Research Manager, emphasized the importance of understanding these risks thoroughly. While the most recent quake occurred around 12,000 years ago, predicting the fault's next move requires ongoing investigation.

This initiative underscores the need for vigilance and preparedness in regions facing latent but devastating geological hazards.
